I just downloaded Itunes, I hit sync,(I thought it would load up my current play lists on my iphone) it loaded up all the stupid songs, that come included with windows vista. (How do I delete them??? anyone! I right click on them, and hit delete, and it erases, then comes back at the bottom of the list....)

I would like to take all my songs off of my Iphone and put them in my computer/itunes, so I can continue buying new songs.

I bought a new computer and installed itunes on it, however when I purchased a song through the music store, I can't get it on to my iPhone. Anyone know or if you can guide me to the right spot, it would be appreciated. Thanks.
